Application filed December To all whom-it may concern Be it known that I, ADOLF momm citizen of the Empire of Germany, residing at Berlin, Germany,

have invented certain new and useful lmprovem cuts in Apparatus for Igniting Gas-Jets, ofwhich the following is a specification. v V

1 The invention relates to an apparatus for igniting gas-jets; and the object of the same is to provide an apparatus which can be constructed in various forms a (1 arranged out side of the jet.

of, construction and sectional elevation showing A further object is to regulate in the most simple and practical manner, without the aid of complicated mechanism, the supply and the shutting 0d of the gas from the burner and the igniting device proper;

The invention consists of certain features combinations of parts to be hereinafter described and then claimed.

In the accompanying drawings, Figure l is a the main form of my igniting apparatus for gas-jets, in which platinum wire.

the same is automaticallyregulated. Figs. 2" and 2 'are side elevations looking from different points of the rotary plug-valve. Fig. 3 is a vertical section of a modification .in which the igniting device is operated electrically. Fig. 3 is a view looking toward the left of Fig. 3 without the casing and contained parts to show more clearly the carrier for the Fig. 3 is an elevation of the interior parts of the casing shown in Fig. 3.

In the main form of the invention (shown in Fig. 1) the gas enters the inlet or supply pipe 0, from which extend branch pipes d and e. The inlet or supply pipe 0 supports a casing a, which'incloses the branch pipes and which is closed by a bottom piece b. At the upper end of the branch pipe e and comma nicating therewith is arranged an expansible bag or diaphragm f, which is crowned by a cap p, pivotally connected with a lever q, mounted directly upon a rotary plug-valveg that turns in a suitable bearing at the upper end of the branch pipe cl. From the plug valve g there leads a bypass tube it, which has two branches 1 and m, the pipe m supporting at its upper apertured end a platinum wire 0, which carries the igniting-pellet n. as well as the are inclosed in an The pellet n, and the wire 0, upper end of the pipe m,

. extends a tubular elbow 629,146, dated July is, 1899. I

- igniting sleeve or hood 2', whereby a shifting is rendered impossible. The other branch Z from the by-pass tube it forms an ignitingtube which is provided with a series of peri'orations or apertures Z, that extend helically from a point nearthe lower end of the said igniting-tube to a point on the opposite side the same. .The said series of apertures at the upper end of the igniting-tube extend beyond the gallery or chimney-support. From the bearing for the rotary plug-valve g there also or connecting-piece h, which leads into a screw-threaded nipple t',-upon which the burner is screwed.

The regulation of the gas-admission is effected by means of a rotary pl ug-valve b, the construction of which is clearlyshown in Figs. 2 and 2". The valve 1) is provided with a diametrical passage 7t, which may communicate with the branch pipe 61, and with a groove 0', that maycommunicate with the passage 75, said groove extending nearly but not entirely around the said valve.

Fig. 3 illustrates a construction which is similar to that shown in Fig. 1, excepting that in this case the ignition is effected by electrical andv not by chemical means. On the bottom I) of the casing a there is arranged an insulating-plate which carries two contactpieces 3 and 'r. The contact-piece s is formed with a-shoulder .9, (see Fig. 3 which when the two contact-pieces come tog'etheroloses the circuit. The contact-piece r is provided with a projection to, the purpose-of which will be referred to hereinafter. of the invention the igniting device consists merely of a platinum wire 0, which is held .by two holders U 'u', (see Fig. 3, which are mounted upon an insulating-block y, located at the bottomof the igniting-sleeve z.

The operation 'ofthe constructions described is as follows: .It is assumed that as regards the construction shown iuFig. 1 the gas-cock-controlling pipe 0 is open, so that the gas passes up through the pipe 0 and, dividing, flows into the branch pipes at and e and expands the bag f,- thereby raising the lever q and turning the plug-valve g, which in its original position already permitted the gas to pass through the branch pipe (I- to the of the relative positions of the parts n and o In this form ot the igniting-tube and at the upper endot become incandescent.

by-pass 7t, so that it reached the tubes m and land caused the pellet a and the wire 0 to The gas contained in the igniting-tnbe Z is ignited first at the lower apertures of the series of apertures Z, and then at each of the uppermost apertures in succession, so that in consequence a pointed flame is produced at the top of the igniting-tube. Meanwhile the bag f, having continued to expand, has raised the lever q still farther and has allowed the gas to pass through the passage k in the plug and also the connectingpipe 77. to the burner, while at the same time the supply to the by-pass 70 has been shut off by the closed portion of the plug, which is between the ends of the groove 0 therein. The pointed flame from the igniting-tubel now ignites from below the gas that is escaping at the top of the burner, and immediately after so doing it is extinguished, because in the meantime the supply of gas through the by-pass 70 has ceased. So long as the gas from the burner is burning the bagf is expanded and retains the lever q in its raised position that is to say, it keeps the rotary plug-valve g in its full open position. When the gascock is turned to shut off the gas, of course the flame from the burner becomes smaller, and when the remainder of the gas from the bagf has been consumed the flame is entirely extinguished.

As regards the construction shown in Figs. 3, 3, and 3 let it be assumed that the gascock-controlling pipe 0 is opened. The expansible bag f then expands, raising the lever q, and the latter, by engaging the projection 10 on the contact 7", bringing the two contactpieces 8 and 9' into contact at s. The circuit is thus closed, and the platinum wire o,which is included in the circuit, is caused to become incandescent. In this case also a pointed flame is produced at the upper end of the igniting-tube; but in the meantime the bag f has been expanded and has risen quite high and the contact-pieces s and 1' have again moved out of contact, the projection 10 of the contact-piece 7' having moved into a recess in or formed by a bend in the lever q. Then the gas-cock is closed, the same effect is produced as in the construction shown in Fig. 1- that is to say, the flame at the burner is extinguished after all the gas from the bagfhas been consumed.

From the above description it will be perceived that in the constructions shown and described the igniting device is arranged outside of and near to the burner proper, which has the result of diminishing the wear of the device. In both forms of the invention a pointed flame is produced through the medium of. the igniting-tube with the series of apertures, which flame ignites the gas from the burner proper from below and diminishes the wear of the incandescent mantle.

Having thus described my invention, I claim as new and desire to secure by Letters Patent In an igniting apparatus for gas-jets, the combination,with asupply-pipe provided with branch pipes, of an expansible bag connected with one of the branch pipes, a rotary valvein the other branch pipe, provided with a lever connected with said expansible bag, a burner, a connecting-tube leading from said rotary valve and forming a by-pass, an igniting-tube connected with the by-pass, and an igniter arranged opposite the igniting-tube, under the influence of the gas escaping from said bypass, substantially asset forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

ADOLF BACIINER.
